Addition-Subtraction Thirty-one

Addition-Subtraction Thirty-one builds on the target-31 card idea by allowing Grade 2 students to use both addition and subtraction. With five values in a hand, students look for an expression that equals 31, so a successful solution may require them to combine positive and subtractive moves rather than simply total everything.

Use it in a small group when students need mixed-operation practice and are ready to experiment with more than one possible expression. Ask students to share different ways the same set of numbers could reach the target.
